Application filed March 31, 1916. Serial No. 87,987.

To all whom t may concern:

Be it known that I, WILLIAM A. LOTZ, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Bag-Frame Fasteners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

The present invention relates, generally, to improvements in that class of fastening or locking devices, such as are usually employed with the hinged sections of bagframes, and the like; and, the invention has reference, more particularly, to a novel bagframe fastener which is very simple in its construction and in its operation, and which comprises in connection with a shell or casing adapted to be secured upon one of the frame-sections, a slide and its catch-engaging post or linger, a push-device or button for releasing a retaining spring` from its holding engagement with said slide, and means for bringing the said slide after its release again into its holding engagement with said retaining spring.

rlhe present invention has for its principal objects to provide a bag-frame fastener of the general character just stated; and, furtherinore, to provide a fastening device for bag-frames, and the like, which has a neat appearance, and in which there are but few internal parts, such parts being arranged so as to render the operations of i said fastening device easy and effective, and

at the same time obviating the liability or chance of any disarrangement of the various parts.

ther objects of the present invention not at this time more particularly enumerated will be clearly understood from the following detailed description of the present invention.

With the various objects of the present iiwention in view, the said invention consists, primarily, in the novel bag-frame fastener hereinafter set forth; and, the invention consists, furthermore, in the novel arrangements and combinations of the several i devices and parts, as well as in the details of the construction of the said parts, all of which will be more fully described in the following specification, and then finally embodied in the clauses of the claim which are appended to and which form an essential part of the said specification.

The invention is clearly illustrated in the accompanying drawings, in which Figure l is a plan or top view of a bagframe fastener representing one embodiment of the principles of the present invention, said view illustrating the fastener in its mounted position of one of the usual bagframe sections and in its locked engagement with the other frame-section; and Fig. 2 is a front or face view of the said bag-frame fastener, and a longitudinal vertical sectional representation of the frame-section upon which the fastener is mounted, as well as a transverse sectional representation of a catch with which the other framesection is provided and with which catch a locking bolt or post of the said fastener is shown in its locked or holding engagement. Fig. 3 is a bottom view of the said bag-frame fastener; Fig. 4L is a horizontal sectional representation, said section being taken directly beneath the top plate of the shell or casing of the fastener; Fig. 5 is a longitudinal vertical section of the fastener, said section being represented as taken on line 5-5 in Fig. 1, looking in the direction of the arrow a3,- Fig. 6 "is a similar sectional representation of the same parts shown in said Fig. 5, but illustrating the slide-retaining spring in its depressed position for releasing the slide, and the locking` or holding bolt or post from its retained engagement with the hasp or catch of the one frame-section; and Fig. 6a is a central longitudinal vertical section. of the bag-frame fastener, said Figs. 3, et, 5, G and 6at being made on an enlarged scale. Fig. 7 is a front o-r face view of a modified form of bag-frame fastener, but still embodying the principal features of the present invention and a longitudinal vertical sectional representation of the one frame-section upon which the fastener is mounted, as well as a transverse sectional representation of the hasp or catch with which the other frame-section is provided and with which hasp or catch the locking bolt or post of the said bag-frame fastener is shown in its locked or holding engagement. Fig. 8 is a bottom view of the said bag-frame fastener.;

Fig.V 9 is a horizontal sectional representacasing of the fastener; Fig'. 10 isa longitudinalvverticalsection of the said fastener, similar to theV section represented in said Fig. 5 above-mentioned; and Fig. 11 1s a central longitudinal vertical section of the said bag-frame fastener, said Figs. 8, 9, 10

and 11 being all made on an enlarged scale.

Similar characters of reference are employed in all of the said'above described views, to indicatev corresponding parts.

l Referring now to the 'several figures, the reference-characters 1 and'2 indicate frag` mentary parts of the two usual hinged members kof a bageframe, adapted to be closed so that the frame-section 2 will lie Vwithin the fra1ne-section 1.V Ait the'preper point, the said frame section2 is provided with the usual inwardly extending hasp or locking member 3. Y

Referring now more lparticularly tofFigs. 1 to 6 inclusive, the reference-character 4 indicates Va main chambered shelloi casing, com'prising longitudinally extending sides 5, ends 6'and 7,' and a top 8. Extending from the lower marginal edges. of th'e said ends (i and 7 are suitably formed fastening lugs, as '9, which are inserted in the lugreceiving holes or slots 10 correspondingly disposed in the frame-section 1, and are suitably bent against the 'inner face of the said frame-section for permanently securing the said shell or Acasing. 4f in its position upon the Vupper face of said frame-section. The end 6 of the said shell or easing is made with ,a finger or push-piece receiving opening, as 11, and in the top 8 is a suitable push-button' receiving hole 12. Y Y

Thev referencefcha-racter 13V indicates a suitably V.formed cup-shaped element which may be'employed, if desired, being suitably .secured upon the outer face of said top 8,

by means of fastening lugs 14,01' other suitable fastening means, andV surrounding the said opening 12, ina-manner substantially as indicated inv Fig. 6 of the drawings.

Suitably'secured to the inner face of the end 7 of thesaidshell or casing 4, by means of a rivet, as 15, or any other suitable fastening means, isw the attaching end-portion 17 ofv a longitudinally extending leaf-spring 16, the said spring being arranged in alinement 'g beneath the push-button receiving hole 12in'the'top 8 of the shell or casing, and being provided upon Vits freexend-portion with an upwardly projecting slide-retaining orholding teat or projection, as 18, formed with an inclined or chamfered surzface-portion19. suitably, disposed within the said hole 12 isa push-'buttomras 20, the lower portion of said button Vprojecting into the chambered part of the shell or casing 1, `and restingldrectly upon thel upper surface of said leaf-spring 16, as shown, and for the purpose of the depressing the said free end-portion of the' said spring, as will be clearly eif'ident'from an inspection of the several figures of the drawings. To prevent displacement of the said push-button, its lower end-portion is made with a retaining flange 21 somewhat larger in cross-area than that of the hole 12, as shown. Other means may, however, be employed to prevent the outward displacement of the said push-button 20, as will be evident.

VMovably disposed within the chambered part of the said shell or casing L1, and capable of a sliding movement, back and forth, between the longitudinally extending 'sides 5, is a retaining slide comprising a 'mam body or plate 22, a pan' of longitudinally extending marginal guide-members, as 23, projecting upwardly and at right angles from -the said body orV plate, and a pair of longitudinally extending fingers 24.

'Mounted upon said fingers 2l are the one Vwhich extends into andthrough the previously7 mentioned receiving opening 11 in the end 6 of the main shell or casing L1. At the proper location, one of the said guidenieinbcrs 23 of the slide is providedl with a marginal retaining lug or finger, as 27,

`which extends laterally or crosswise, with relation to the main shell or casing L1, above the upper surface of the leaf-spring 16, and under normal initial conditions is in retained or held engagement with the teat or projection 1S of the leaf-spring, as indicated in Figs. i and 5 ofthe drawings. Suitably connected with and extending in a downward direction from the lower face of the said main plate or body 22 of the slide is the usual locking post or hasp-engaging finger 2S of the bag-frame fastener, said post or finger extending into and through and being slidably disposed in a longitudinally disposed slot 30 of the closing or bottomi-plate 29 with which the shell or casing L1V may be provided, and a corresponding opening 30. in the frame-section 1, clearly evident from an inspection more particularly of Fig. Ga of the drawings.

In Figs. 1 to 5 inclusive, I have shown the several elements of the bag-frame fastener kin their locked or retained engagement, when the post or finger 28 is in its locked or holding engagement with the hasp of the frame-section 2, to retain the two frame-sections 1 and 2 in their closed relation.

VThe operation of the device will be clearly understood from an inspection of Figs. cl, 5

and 6 of the drawings. Vhen the push-button 20 is depressed, the leafspring 16 is caused to assume the lowered position shown in Fig. 6 of the drawings, thus withdrawing the stud or projection 1S from its holding engagement with the lateral extending retaining lug or linger' 27 of the slide. Immediately, the compressed coiled springs 25 will cause the slide to move in the direction of the arrow y, in Fig. 5, so as to ,bring the said lug or linger 27 upon the opposite side of the stud or projection 18, with the push-piece 26 of the slide projecting much farther from the opening 11 in the end 6 of the main shell or casing of the fastener. lhen the said lug or linger 27 has passed beyond the said teat or projection 18, it will be evident that the locking post or hasp-engaging finger 28 will also have moved from its retained engagement with the hasp 3 of the frame-section 2, so that the two frame-sections 1 and 2 can be brought into their opened relation. At the same time, the leaf-spring .16 has also returned to its normal initial position. To bring the various devices and parts again into their locked relation, the two-frame sections 1 and 2 are first closed, so as to bring the hasp 3 into its alined relation, or into the path of movement of the post or hasp-engaging linger 28. The push-piece 26 is now forced in an inward direction, so as to move the slide in the reverse direction from that indicated by the arrow y, the lug or linger 27 riding upon the inclined surface 19 of the stud or projection 18, and over the latter, thus depressing the leaf-spring sufliciently, until the said lug or linger 27 has passed said stud or projection 18, with the parts again in their locked or retained relation, as will be clearly evident and as indicated in Figs. l and 5 of the drawings.'

Referring now to the modilication of bagframe fastener illustrated in Figs. 7 to 11 inclusive, the main box, shell or casing comprises a top 31, formed with an opening 32, longitudinally extending sides 33, and the ends 34, the opening in one of the ends, as in the construction herein-before described, being dispensed with in the present construction. The ends 311 are provided with the usual fastening lugs or tongues, as 35, which are inserted through the usual o penings in the frame-section 1 and are clamped upon the inner face of the said frame-see tion in the usual manner. Attached to the inner face ofone of the said ends 34, by means of a rivet 36, or otherwise, is the attaching end-portion 38 of a longitudinally extending leaf-spring 37, the said spring being arranged in alinement beneath the said opening 32', and being provided upon its free end-portion with an upwardly projecting slide-retaining or holdin stud or projectio.q 39, formed with an inc ined or chamfered surface-portion 40. Rotatably mounted upon the upper surface of the said main box, shell or casing is a manipulating element or linger-piece, as 41, provided upon its lower part with a reduced necleportion 12 which extends into the said opening 32 and projects beneath the lower surface of the said top, substantially as illustrated in Figs. 10 and 11 of the drawingsl The said manipulating element or finger-piece 41 is formed with a cup portion, as 4.3, in which is loosely disposed a push-button 4:11 provided upon its lower portion with an annular flange, as L15, resting directly upon the upper surface of the said leaf-spring 37, as shown in said Fig. 10. Suitably mounted and secured upon the said neclcportion 42 of the manipulating element or linger-piece L11 is a disk-shaped element, as 416, having an arc-shaped portion provided with teeth (17, and having a pair of angular portions, as 18 and L19, the purposes of which will be presently described. Movably disposed within the said box, shell or casing, and capable of a slid ing movement, back and forth, between the longitudinally extending sides 38, is a retaining slide comprising a main body or plate 50, anda pair of upwardly projecting and longitudinally extending marginal guide-members, as 51 and 52, the member 51 being made with ratchet-like teeth 53, or the like, adapted to mesh with the herein-before-1nentioned teeth 417 of the disk-shaped element 116. The other member 52 of the said slide is provided with a marginal retaining lug or linger, as 54, which extends laterally or crosswise, with relation to the main shell or casing, and under normal initial conditions is in retained or held engagement with the stud or projection 39l of the leaf-sjning 37, as indicated in Figs. 9 and 10 of the drawings. At its one end, the said main body or plate 50 has a longitudinally extending linger, as 55, upon which is mounted the one end-portion of a coiled spring 56, ythe other end-portion of said spring bearing upon the end-portion 38 of the leaf-spring 87. Suitably connected with and extending downwardly from the lower face of the said main body or plate 50 is a locking post or hasp-engaging linger 57 which extends'intb and through, and is slidably disposed in a longitudinal slot or opening, as 59 of a closing or bottom-plate 5S with which the shell or casing of the bagframe fastener may be provided, and the corresponding opening 30 in the frame section 1. 1n said Figs. 7 to 11 inclusive, the several elements of the bag-frame fastener are shown in their locked or retained engagement, when the said post or finger 57 is in its locked or holding engagement with the hasp 3 of the frame-section 2, to retain the two frame-sections 1 and `2 in their closed relation.

The operation of this modified bag-frame fastener is as follows :--IVhen the push-button 44 is depressed, the leaf-spring 37 is forced in a downward direction, sufiiciently to withdraw the stud or projection 39 from Y its Yholding engagement with the laterally extendingretaining lug or finger 54 of the slide. Immediately, the compressed coiled spring 56 will cause the slide to move inthe direction of the arrow e, in Fig. 10, so asv to bring the said lug or inger54upon the opi 'posite side of the retaining stud or'projecktion 39.' When the` said lug orfinger 54 has thus passed-beyond the said stud or projection39,`it will be evident that the locking postV or has'p-engaging finger 57 will also have moved from its retained engagement withthe hasp'3 of the frame-section2, so that the two frame-sections 1 Vand 2 can be brought intotheir opened relation. At the same time, the leaf-spring 37 has also returned to its normal initial position. During the movement of the Yslide in the direction of the arrow z, the teeth 53 of the lslide has rotated the toothed disk-shaped element 46 yin the direction of the arrow u, until the corner# portion 48 is broughtl into contact with the marginal guide-member 51, which as will be evident limits and controls the movement of the slide in the direction of the arrow .2. p To bring the various kdevices and parts again into their locked relation, the two frame- Ysections 1 andY 2 are first closed, so as to move until the said lug or finger 54 has passed ,said

stud or. projection39, with the parts again intheir locked or retained relation, as will be clearly evident.

Of course, I am'fully aware, that changes may be made in the general arrangements and combinations of the several devices and parts, as Vwell as inV the'details of the construction of the said parts, without depart` ing from the scope of the present invention as set forth in the foregoingspecification, and as defined in they clauses Vof the claim which are appended tothe said specification. Hence, "I do not limit my present invention to the exact arrangements and combinations `ofthe Vdevices and parts as described in the saidspecification, nor do I` confine'myself to the exact details of the construction of the surface of said slide, a push-piece within the opening in. said top for depressing said spring, and a retaining means connected with saidspring normally in Vholding engagement with said slide. y
